Have tried all the solutions to get this system up and running. I am running a windows/MAC network; my ISP is TKS (Germany) into a DLINK ADSL modem DL-360T into a Apple Extreme router then into a DLINK DGS 2205 Gigabit switch; hooked to the switch is a windows computer, IMAC computer, and the Linksys PAP2 V2 phone adapter. Have tried all the installation recommedations but nothing. Can anyone help. thanks

I have tried going from the router into phone adapter, and then I tried going from the DSL modem directly into the phone adapter. I just found out that Apple Extreme doesnt not support port forwarding.

Ordinarily you do not have to forward ports for a Vonage unit to work. Is the Airport Extreme set up as a DHCP server? What does the PAP2 do or not do when it's plugged directly into the Extreme? What are the various lights doing (off, on solid, flashing, color)?

Please provide the rest of the technical details listed in the sticky message at the top of the forum.
